Secure Programming for Linux and Unix
"This is the main web site for the Secure Programming for Linux and Unix HOWTO. This document provides a set of design and implementation guidelines for writing secure programs for Linux and Unix systems. Such programs include application programs used as viewers of remote data, web applications (including CGI scripts), network servers, and setuid/setgid programs. This document includes specific guidance for a number of languages, including C, C++, Java, Perl, Python, and Ada95."
Home Linux Server
"For less than $1,200, you can build a very capable server with gobs of storage and enough processing horsepower to pull multiple duties serving up a printer queue, web pages, FTP, DHCP, and SAMBA, and more. And, if you've got some old parts to scavenge, and are working within a tight budget, you can still put together a solid server for under $600. So here's how to build out the heart and soul of your home network, the home server. Or, if you've got an old box you're looking to put out to pasture, it can be turned into a serviceable home server with a few spot upgrades."
Recursive Make Considered Harmful
"For large UNIX projects, the traditional method of building the project is to use recursive make. On some projects, this results in build times which are unacceptably large, when all you want to do is change one file. In examining the source of the overly long build times, it became evident that a number of apparently unrelated problems combine to produce the delay, but on analysis all have the same root cause."
$#!%% Regular Expressions
"Ask any relatively-experienced *NIX user to list his top ten favorite things about the operating system, and you're almost certain to hear him mutter, somewhere between "99% uptime" and "remote system reboots", the phrase "regular expressions".
Ask any relatively-experienced *NIX user to list the ten things he hates most about the operating system, and somewhere between "zombie processes" and "installation", he's sure to spit out the phrase "regular expressions"."
